Newtonian Mechanics II: Frictional Force Drag Force Centripetal Force
... NOTE: A centripetal force can be a frictional force, gravitational force, or any other force. Basically, it is another force that is causing an object to go in uniform circular motion. For instance, the gravitational force of the Sun causes the planets to rotate around it. NOTE: If a problem is ask ...

... 3. Draw the components for any forces or acceleration that does not lie along the X or Y axis, and identify the angle that is given (or being looked for). 4. Pick one direction and write down all the forces or components of forces in that direction, using positive and negative signs to identify thos ...

Motion and Forces
... Newton’s Third Law • When one object exerts a force on a second object, the second one exerts a force on the first that is equal in size and opposite in direction. – “To every action, there is an equal and opposite reaction.” – Example – when you jump on a trampoline the trampoline exerts the same ...

Forces
... Cancellation? • Equal and opposite forces cancel each other out, but only when applied to same objects. • Action and reaction forces do not cancel out because they act on different objects. • If you pushed on a friend’s hand with your hand with the same amount of force, neither of you would move. B ...

General Description of Motion
... • We’ve seen that the translational motion of a complicated object can be accounted for by the motion of the center of mass • Now, we turn to all the other motions with respect to coordinate system moving with the center of mass • These are of two types: coherent and incoherent with coherent motions ...

... 1. Given r(t), find v(t) and a(t), by differentiation. 2. Given a(t), find v(t) and r(t), by integration. Additional Fact: Newton’s Second Law states that F = ma, which thus relates force on an object to its acceleration, which will be a starting point many times for #2. Practice: 1. Find the force ...
